Analysis of Gene Expression Profiles of Rice Mutant SLR1 Based on Microarray Data

Gibberellins are an important class of plant hormones.They play an important regulatory role in all stages of growth and development of higher plants.The use of mutants to study gibberellin metabolism and signal transduction pathways is currently a research hotspot.This article takes the data of Affymetrix chips of rice as an example,bioinformatics method was used to study rice SLR1 mutant and mine differentially expressed wild-type genes,thus exploring the expression regulation network of gibberellin signaling pathway-related genes.

Chirped Fiber Bragg Gratings for Optieal Fiber Dispersion Compensation

The use of α-power chirped fiber Bragg gratings for dispersion Cancellation in an optical fiber link is discussed.Numerical and theoretical investigation of recompressing the dispersion-broadened pulse by usingα-power chirped gratings is made,which shows that,the dispersion-broadened Gaussian pulse after l00km standard fiber(with zero dispersion atλ=1.3μm)trnasmission atλ=1.55μm with initial width of T_(FWHM)=33ps(full width at half maximum)can be perfectly recompressed with the peak reflectivity of 82%by using a 30mm longα-power chirped fiber grating with properαvalue and optimal grating parameters.

Pharmacist-led interventions to reduce inappropriate drug use in the orthopaedics department in China

As the demand for pharmaceutical services continues to grow, more and more attention has been paid to the pharmaceutical care effect. However, in China, the training pathways and practical work of clinical pharmacy are still in the exploratory stage. In the present review, we aimed to discuss the impact of pharmacist-led interventions in reducing inappropriate drug use in orthopaedics. Results showed clinical pharmacists can assist orthopaedists and nurses in the rational use of medication in all aspects of antibiotic therapy, pain control and anticoagulation therapy. The clinical interventions by pharmacists have greatly reduced medication errors and medical costs. However, there is still a long time to develop pharmacy service, improve the professional quality of pharmacists and enact the Chinese Pharmacist Law.

A low-temperature synthesis-induced defect formation strategy for stable hierarchical porous metal–organic frameworks

A stable hierarchical porous metal-organic framework PCN-56 with abundant Lewis acid sites(denoted as Defective-PCN-56) was synthesized by the low-temperature synthesis-induced defect formation method.The existence of mesopore in structure was confirmed by N2 sorption isotherm and the successful encapsulation of large dye molecules.The Defective-PCN-56 has higher loading capacity toward anti-cancer drug Doxo compared with that of "nearly ideal-crystal"(denoted as Ideal-PCN-56)synthesized at high temperature,showing potential application as drug carrier.The low-temperature synthesis-induced defect formation strategy presented here provides a new and facile way to synthesize stable MOFs with the combination of intrinsic micropore and additional mesopore as well as abundant Lewis acid sites.

Unseen head pose prediction using dense multivariate label distribution

Accurate head poses are useful for many face-related tasks such as face recognition, gaze estimation,and emotion analysis. Most existing methods estimate head poses that are included in the training data(i.e.,previously seen head poses). To predict head poses that are not seen in the training data, some regression-based methods have been proposed. However, they focus on estimating continuous head pose angles, and thus do not systematically evaluate the performance on predicting unseen head poses. In this paper, we use a dense multivariate label distribution(MLD) to represent the pose angle of a face image. By incorporating both seen and unseen pose angles into MLD, the head pose predictor can estimate unseen head poses with an accuracy comparable to that of estimating seen head poses. On the Pointing'04 database, the mean absolute errors of results for yaw and pitch are 4.01?and 2.13?, respectively. In addition, experiments on the CAS-PEAL and CMU Multi-PIE databases show that the proposed dense MLD-based head pose estimation method can obtain the state-of-the-art performance when compared to some existing methods.
